Go 1.24 Swisstable Impact on Memstore

[stefanLeo]

Hi all

With the latest version of Go arriving and featuring an all new hash table implementation based on Abseils swisstables: Do you see any improvements or issues that may arise with NATS especially using the memstore option?

https://www.bytesizego.com/blog/go-124-swiss-table-maps
states faster inserts, lookups, but maybe slower deletes.

Do you plan to investigate/test that change in terms of performance impact on NATS?

Thank you &
BR

Yes, we are already evaluating Go 1.24 and it is our intention that NATS 2.11 will be released with it.

Not currently aware of any particular issues — on the whole the changes to mutex scaling and the swissmaps look promising.
